Regarding the COVID-19 laboratory biomarkers, the mean lymphocyte count was low (0.63 [0.43–0.90] × 109/L) and the plasma levels of D-dimer, ferritin, and IL-6 were notably elevated with median values of 1.12 [0.59–3.52] mg/L, 1389.0 [821.0–2250.0] ng/mL and 114.0 [47.5–181.4] pg/mL, respectively. This evidence concerns the gene IL6 and COVID-19.
